Yes. You can. Which auction are you looking at? Depending on the size and weight, I will most likely not add the $2 shipping charge from this auction. Like if you win the beauty, makeup lot, I will only just charge shipping from that auction and waive shipping for this one.
I can go $2.50 on that. It would be first class, 2-5 business days. That would cover the paypal fee, s&h, plus tracking. My local USPS always gives me trouble about weight and packaging, so I generally print my labels. Good Luck:)
They will be. It is easier to ship them both without using seperate materials or getting two labels. I had a high value auction with free shippingg once. Everything was shipped direct from retailer. But the winner of both auctions did not bother to tell me she was the same person, and because I had so many auctions open and didn't notice myself, I ended up getting hit with shipping in the double digits. By the time I realized it on my own, the package had already been prepared for post. So I 100% do not mind combining shipping if you win two auctions.
